This week - Arizona wrong way, electricity OK, Smart in Manchester, public concern and Tesla

Home / News | posted on 03 08 2017 News Roundup looks at an innovative wrong-way detection system being deployed in Arizona on I17, in the first of its kind in the US; will electricity grids cope with the demands posed by increasing numbers of electric vehicles; the new smart card being used on trams and buses in Manchester; public concerns about the use of emerging transport technologies and Tesla revenues double in the last quarter.

Arizona 'wrong-way' first

The State of Arizona will be the first to install a detection and warning system to tackle the issue of 'wrong-way' drivers on an Interstate. The Arizona Department of Transportation (ADOT) has given the go ahead for the construction of the $3.7m pilot project along 15 miles of Interstate 17 in Phoenix. The issue of vehicles driving on the wrong side of a divided dual-carriageway can have catastrophic results due to the closing speeds involved with oncoming vehicles. The proposed system will make use of optical vehicle detectors located at the top of exit ramps to detect vehicles entering the wrong way and these will trigger warning signs to warn the offending driver of their mistake. The unit will also notify the authorities, so that they can take action. Further units will also be located on the mainline carriageway, which if the vehicle continues, will be used to trigger VMS to warn approaching drivers and close on ramps to minimise the possibility of accidents. In the event of drivers becoming aware of an approaching vehicle on the wrong side of an Interstate or motorway, they are advised to slow down and move to an inside lane if possible.

National grid will cope with move to electric cars

Analysis by Cambridge Econometrics has found that the move to ban new vehicles with internal combustion engines in the UK by 2040 would increase demand for electricity by less than 10%. Research by UK Power Networks shows that car charging reaches a peak two hours later than expected, at 9pm, which is outside of overall peak demand. Further encouragement to time-shift charging could be encouraged by introducing specialist 'time of use' electricity tariffs. Interestingly, the effect of charging from fossil fuel generated electricity will still reduce carbon emissions because electric vehicles are more efficient, according to Carbon Brief. In addition, the emissions associated with the production of vehicle batteries is apparently offset by the carbon savings they achieve in use in their lifetime.

Manchester smart cards allow multimodal journeys

Greater Manchester's 'Get Me There' smart card system now allows passengers to use a single system to travel on all trams and buses within the city for the first time. The facility works with the different bus operator companies to provide a single means to pay for travel. "The expansion of Get Me There will certainly help make travel easier and, for the first time, enable people across Greater Manchester to hop on and off trams and buses with their smartcard" said the Mayor of Greater Manchester Andy Burnham.

Are the public worried about emerging transport technologies?

With the huge investments that vehicle manufacturers and technology firms are making for a diverse range of emerging technologies, which could form important aspects of our transport system in the next few years, are the public convinced that these will be a good idea? Despite the goals of greater convenience, reduced congestion, better environmental health, improved safety and better use of time, a survey carried out by the RAC found that, 70% of British motorists are concerned about the reliability of the computer software which will be used by autonomous vehicles. They also found that nearly half of drivers are not excited by the prospect of driverless cars and 62% are actually scared of the thought of them on the road. To convince potential users of the benefits of new technologies, companies will need to be more transparent about the successes and failures they have faced in development and testing.

Tesla revenues double

Elon Musk's company has reported increased revenues of $2.8bn in the last quarter, up from $1.3bn for the same period last year. However, losses of $336m also increased from the $293m last year. But with 1800 reservations a day for the company's new 'affordable' $35,000 Model 3, Tesla has informed shareholders that it expects revenue to grow "significantly" in the second half of the year, while expenses hold steady.
